How to Buy Treasury Bills and Bonds in Kenya (2026 Guide)
A few years ago, investing in Kenyan government securities was an incredibly frustrating process. You had to physically visit a Central Bank of Kenya (CBK) branch, fill out endless paper forms, submit physical passport photos, and wait weeks for manual processing.
That system is dead.
Today, the CBK manages all retail and corporate investments through the DhowCSD digital platform. Whether you are living in Nairobi or working in the diaspora, you can open an account, place bids, and track your interest payments entirely from your smartphone.
If you are looking for a predictable, risk-free place to park your capital, lending money to the Kenyan government remains one of the smartest financial moves you can make. Here is exactly how to do it.
Treasury Bills vs. Treasury Bonds: Which Should You Buy?
Before downloading any app, you need to understand what you are actually buying. When you purchase these securities, you are essentially giving a loan to the Government of Kenya. In return, they pay you interest.
The primary difference between the two lies in the duration of the investment and how the interest is paid.
Treasury Bills (T-Bills)
Treasury bills are short-term investments. The government issues them in three durations: 91 days, 182 days, and 364 days.
T-Bills do not pay regular interest. Instead, they are sold at a discount. If you want to invest KES 100,000 at a 10% interest rate, you will pay the CBK approximately KES 90,000 upfront. When the bill matures, the CBK credits the full KES 100,000 to your bank account. Your profit is the discount amount.
Treasury Bonds (T-Bonds)
Treasury bonds are medium to long-term investments. Their durations range from 1 year up to 30 years.
Unlike T-bills, bonds pay periodic interest, called a "coupon." The CBK pays this interest into your commercial bank account every six months until the bond matures. At the end of the bond's life (maturity), you receive your initial principal investment back.
The Minimum Investment Requirements
| Security Type | Duration | Minimum Investment Amount | How Returns Are Paid |
|---|---|---|---|
| Treasury Bills | 91, 182, or 364 Days | KES 100,000 | Sold at a discount (lump sum at maturity) |
| Treasury Bonds | 1 to 30 Years | KES 50,000 | Semi-annual interest payments |
Note: Any amount invested above the minimum must be in multiples of KES 50,000.
Step 1: Requirements for Opening a DhowCSD Account
To invest directly with the Central Bank without going through an expensive broker, you must open a DhowCSD account. You need four things:
- An original National ID or valid Passport.
- Your KRA PIN certificate (mandatory for Kenyan residents).
- An active commercial bank account in Kenya.
- A clear passport-style digital photo.
Step 2: Registering on the DhowCSD Platform
You can do this via the web portal (dhowcsd.centralbank.go.ke) or by downloading the CBK DhowCSD mobile app from the Google Play Store or Apple App Store.
- Create a Profile: Enter your email, create a username, and set a strong password.
- Select User Type: Choose "Physical Person" if you are investing as an individual.
- Fill in Details: Enter your personal information exactly as it appears on your National ID.
- Add Bank Details: Input your commercial bank account number. The CBK will send your interest payments and maturity refunds directly to this account.
- Document Upload: Upload your ID, KRA PIN, and photo.
- Bank Verification: Once you hit submit, your application is routed to your commercial bank. The bank must verify that the details you provided match the details on your bank account. This usually takes 24 to 48 working hours.
Once your bank approves the application, you will receive an email confirmation with your official CSD Account Number. You are now ready to invest.
Step 3: Understanding Bidding (Competitive vs. Non-Competitive)
When the CBK wants to borrow money, they announce an "auction." You participate by placing a bid. You have two bidding options:
Non-Competitive Bids (Best for Beginners)
You simply tell the CBK how much money you want to invest (e.g., KES 100,000). You do not specify an interest rate. Instead, you agree to accept the average market interest rate determined by the auction.
Your bid is guaranteed to be accepted.
If you are investing under KES 20 Million, this is the safest route.
Competitive Bids (For Advanced Investors)
You specify exactly how much you want to invest and the specific interest rate (yield) you want. If your requested rate is too high compared to what the market dictates, the CBK will reject your bid, and you will miss out on the auction.
Step 4: How to Place a Bid on DhowCSD
Once an auction is announced (you can check the CBK website or the DhowCSD app for upcoming prospectuses), follow these steps:
- Log into your DhowCSD app or web portal.
- Navigate to the Auctions or Securities tab.
- Select the specific T-Bill or T-Bond you want to buy.
- Click Create Bid.
- Select Non-Competitive (unless you are experienced in yield mechanics).
- Enter the Face Value (the amount you want to invest).
- Select your Source of Funds (e.g., Local, Salary, Business).
- Accept the legal terms and click Place Bid.
Step 5: Payment and Settlement
Submitting a bid does not pull money out of your bank account automatically.
After the auction closes, the CBK will publish the results. If your bid is successful, log into your DhowCSD account and check the Transactions tab. Here, you will find:
- The exact amount you need to pay (especially for T-bills, which are discounted).
- Your Payment Key (a unique reference number for your transaction).
- The Settlement Date (the strict deadline for payment).
You must transfer the money from your commercial bank to the CBK before the settlement deadline. Cash and physical cheques are no longer accepted. Payments are made via direct bank transfers (EFT/RTGS) using your CSD account number and the Payment Key as the reference.
A Note on Taxes (And the IFB Loophole)
The Kenya Revenue Authority (KRA) taxes the interest you earn from government securities. The CBK automatically deducts this withholding tax before sending the money to your bank account.
- 15% Withholding Tax: Applies to all Treasury Bills and any Treasury Bond with a duration of less than 10 years.
- 10% Withholding Tax: Applies to Treasury Bonds with a duration of 10 years or more.
The Tax-Free Exception: Infrastructure Bonds (IFBs)
Occasionally, the government issues Infrastructure Bonds to fund mega-projects like roads and dams. These bonds are incredibly popular because the interest earned is 100% tax-exempt. When an IFB auction is announced, they are heavily oversubscribed, so you must bid early.
Frequently Asked Questions (FAQ)
Can Kenyans living in the diaspora buy Treasury Bonds?
Yes. The DhowCSD platform is accessible globally. As long as you have a valid Kenyan ID or Passport, a KRA PIN, and an active Kenyan commercial bank account, you can register and invest from anywhere in the world.
What happens if I miss the settlement deadline after my bid is accepted?
Failing to fund your accepted bid is considered a default. The Central Bank may penalize you by suspending your DhowCSD account, preventing you from participating in future auctions. Always ensure your funds are liquid and ready before placing a bid.
Can I withdraw my money before the bond matures?
Treasury Bills cannot be easily cashed out before maturity (unless you rediscount them with the CBK at a highly punitive penalty rate). Treasury Bonds, however, are traded on the secondary market via the Nairobi Securities Exchange (NSE). You can sell your bond to another investor through a licensed stockbroker, though the price you get will depend on current market conditions.
Is my money safe with the Central Bank?
Yes. Government securities are considered risk-free investments because they are backed by the full faith and credit of the Government of Kenya. It is the safest investment vehicle available in the local market.
